Internet reliability issues: Slow uploads 0.1mbps

I noticed earlier that upload seemed quite unstable.  I ran a few tests and the first result was less than 2mbps, and the second was 0.1mbps.  This is on a gigabit plan and a brand new cable modem (SB8200 purchased on April 2020).

I already had a tech come out and connect my modem directly to the cable drop.  Althought things did get better for a brief moment, it looks like the line still has intermitten issues and the cable modem is now complaining about the OFDM channel as seen below:

The table below contains the log of events that the SB8200 has detected. This log can be important to the service provider to help diagnose and correct problems, if any should occur.

    I have a quick update as I've been using a tool like PingPlotter to spot check the health of my internet.

    2020-08-06 - Here I restarted the modem as you can see in the PingPlotter

      @Coolsul, I recommend bypassing the router and running pingplotter again to see if there is any change. Please let us know the results. -Allan, Cox Support Forums Moderator.

        Hello Allan,

        I already did that before the tech came out and the results were the same.  My post above was to provide an update on how well my connection was doing from the 6 (with a ton of packet loss) to the 10th (which had none).  I had improved alot.

        Right now, my connection is unusable.  As requested pingplotter w/o google wifi router.

    @Coolsul, Your modem is reporting multiple time out errors and that will cause issues with the service. Are there any splitters or signal amps on the cable line going to the modem? -Allan, Cox Support Forums Moderator

      The tech who came over a few days ago connected the modem directly to the cable drop with a freshly crimped cable.  There is nothing between the COX cable drop on the side of the house and the cable modem.  If you have access to the history of this line you may notice that the signal, since this change has improved and the number of errors has been reduced, but the issue persists as mentioned above.

        Can you try connecting a PC directly to the modem then signing into your https://bit.ly/2h3A2u0 account to run a few speed tests there? -Chris

    The sequence of CM-STATUS Code 16 followed by Code 24 doesn't necessarily indicate a problem. These codes are used to track the number of correctable errors on the OFDM channel and it's normal to have a lot of correctable errors on OFDM. Only uncorrectable errors will cause packet loss or speed issues.But I have noticed that I start seeing more of these CM-STATUS Code 16 messages before bigger problems occur so maybe it's a sign that things are starting to degrade on the cable network.

    The real problem in that log is the T3 timeout. This will cause problems with speed and packet loss. A lot of people have been reporting this recently so I wonder if Cox is having a widespread issue.

    I have been having the same issue for the past 3-4 months. Had about 7 techs come out and look at the problem. Changed out all of the coax cable, changed out pano modem, everything.. One of them told me that there was a 33% packet loss when he would read it from the pole, but when he had the maintenance bucket truck check the main line, they said there was no problem. I will get up to 600-700 mbps at times, but other times I will get 14-15 mbps. Lately it seems like the upload speed has severely been going up and down. It is one of the most frustrating things..
